Rabbit Seesaw By : Dewi 5B
Problem • How to take my rabbit while it is under its cage?
Purpose • Because my hand is not long enough to reach my rabbit, so I need to find a tool to help me do it.
Prior Knowledge • My rabbit cannot grow very big. • My rabbit likes dry food. • Effort is the part where we use our forces and energy. • Load is the part where we put the object that we want to lift(rabbit) • Fulcrum is the balancing part.
Materials • 3 sizes of Rabbit • 1m wood • 1 trapezoid (fulcrum) • Short wood (handle) • 2 axles
Hypothesis • If I create a lever to take my rabbit then I don’t need to use my energy to do it.
Variables • Independent variables: The position of the fulcrum in the lever • Dependent variables: The easier way to get the rabbit. • Controlled variables: The length of the wood, the sizes of the wheel, rabbit and handle.
Background Knowledge • Rabbit likes dry food • This invention is a seesaw • It is a lever.
2. Push the seesaw until half of the seesaw is under the cage.
8. Change the position of the fulcrum then do the same things again
Result The fulcrum which is near the axle is an easier way to take the rabbit. It is because the rabbit is near to us and we can take it easily. If it is far the rabbit can jump and we should do the experiment again and again.
Conclusion My hypothesis was correct because I have done the experiment and prove that I don’t need to use many energy to get the rabbitwith the exception that the position of the fulcrum is near the effort.
